[Boatanchors] LED Replacements for #47 bulbs

[Garey Barrell]

I too got my order from cointaker.  I got only the 'warm white', looking 
for what 'should' be a '#47 color'.

In a Drake T-4X with recently replaced blue filter and white diffuser 
the dial bulb is pretty good.  There is a 'bit' of a hot-spot in the 
center of the dial (out the end of the bulb) but not objectionable.  The 
meter light, which depends more upon 'side' light is somewhat dimmer, 
but adequate.  The color balance is good.  The 'bulb' itself is kind of 
milky in appearance and does a good job diffusing the light, but still a 
small hot-spot.

Overall I'd say they are acceptable replacements in the Drake 4 Line.
